Definitions

  • the invention relates to frozen aerated confections and methods producing them. More specifically, the invention relates to methods for aerating quiescently frozen confections.
  • Unaerated frozen confections such as ice-lollies are conventionally produced by quiescent freezing. In a typical process, the ingredients are mixed, the mix is placed in a mould and the mould is cooled, usually by immersion in a refrigerant. This method has the advantage of being simple and cheap.
  • aerated frozen confections such as ice cream and sorbet are conventionally produced using an ice cream freezer (i.e. a scraped surface heat exchanger). In the ice cream freezer air is injected into the mix as it is beaten and frozen. The beater breaks the air up into small bubbles.
  • the mix cannot be completely frozen in the freezer (since it would set solid) so it is normally drawn from the freezer in a partially frozen state, and placed in a hardening tunnel or blast freezer to complete the freezing process.
  • This process successfully produces frozen aerated confections, but requires expensive and complex equipment.
  • JP 62 296851 describes a process for producing a frozen aerated confection in which carbon dioxide is generated from the reaction between a carbonate and an acid. Gelling stabilisers to encapsulate and thus stabilise the bubbles of carbon dioxide. The mixture is subsequently quiescently frozen, and the gel structure prevents the gas from being lost during freezing.
  • this method has the disadvantage that the presence of relatively high amounts of stabiliser, particularly in the form of a gel, gives the frozen aerated product an undesirable chewy, gummy texture.
  • Water ices are frozen confections that contain sugar, water, fruit, fruit juice or fruit flavouring, fruit acid or other acidifying agent, stabiliser and colour, but little or no fat or milk protein. They have a total solids content of 5 to 35%, typically 10 to 20%.
  • Milk ices are frozen confections similar to water ices, but in addition they contain milk protein (up to about 5%) and a small amount of fat (typically 2-4%).
  • Frozen yoghurt is a frozen fermented dairy product that contains milk protein, fat, sugar and water. Frozen yoghurt is acidic.
  • Quiescent freezing means freezing without agitation.
  • Examples of quiescent freezing processes include freezing a mix in a mould which is immersed in a bath of a chilled refrigerant, such as brine, or placed in a low temperature environment, such as a freezer; and immersing mix directly in a cryogenic liquid, such as liquid nitrogen.
  • Partial slush freezing means freezing with agitation, for example in a scraped surface heat exchanger, to a temperature (typically -1 to -7°C) at which some, but not all, of the ice that will be present in the product at its final temperature (typically -18°C) is formed.
  • An aerated confection means a confection into which gas (which is not limited to air, but includes carbon dioxide or any other suitable gas or mixture of gases) has been introduced in the form of small bubbles.
  • gas which is not limited to air, but includes carbon dioxide or any other suitable gas or mixture of gases
  • Stabilisers are defined as in Arbuckle, W.S., Ice Cream, 4 th Edition, AVI publishing 1986, chapter 6, pages 84-92.
  • Stabilisers include proteins such as gelatin; plant extrudates such as gum arabic, gum ghatti, gum karaya, gum tragacanth; seed gums such as locust bean gum, guar gum, psyyllium seed gum, quince seed gum or tamarind seed gum; seaweed extracts such as agar, alginates, carrageenan or furcelleran; pectins such as low methoxyl or high methoxyl-type pectins; cellulose derivatives such as sodium carboxymethyl cellulose, microcrystalline cellulose, methyl and methylethyl celluloses, or hydroxylpropyl and hydroxypropylmethyl celluloses; and microbial gums such as dextran, xanthan or ⁇ -1 ,3-glucan.
  • Some stabilisers have the ability to form gels under certain conditions. These include locust bean gum, which can form a gel when a mix containing it at a sufficiently high concentration is frozen; sodium alginate and low methoxy pectin, which can form gels on the addition of doubly charged cations such as calcium; / -carrageenan, which can form a gel after heating and cooling in the presence of cations such as potassium or calcium ions; carrageenans can also form gels in combination with milk proteins and locust bean gum; high methoxy pectin, which can gel at low pH and in the presence of high concentrations of sugar; and gelatin forms a gel when heated and cooled. Some mixtures of stabilisers (which do not necessarily separately form gels) can also combine to form gels (under appropriate conditions) such as a mixture of xanthan and locust bean gum.
  • the volume of the displaced water is the volume of the piece of frozen confection.
  • the density of the frozen unaerated mix is determined.
  • the sample is allowed to melt and gently stirred.
  • the melted sample is then placed under a low vacuum in a vacuum oven at room temperature for 5-10 minutes in order to remove the gas bubbles.
  • the de-aerated sample is then re-frozen and its density measured as described in method 1 above.
  • the overrun is calculated from the measured densities of the frozen unaerated mix and the frozen aerated product.
  • a large number of approximately spherical discrete frozen pieces are filled from the base into a cylindrical type cup (height 95 mm, bottom outside diameter 63 mm, top outside diameter 46mm) to a fill weight of 85 g.
  • the base is then sealed on with an iron.
  • Samples are held at -25°C for 30 days. The test is performed by squeezing the pot manually, then opening and upturning it.
  • a squeeze score of 3 is considered the maximum in terms of acceptable flowability.
  • the scores are quoted as the mean values of the scores obtained for six replicate samples.
  • the present invention provides a method for producing a frozen confection having an overrun of at least 15%, which method comprises quiescently freezing a mix containing a carbon dioxide generating composition, characterised in that the mix does not comprise a gel.
  • the carbon dioxide generating composition comprises an acid and a carbonate.
  • the acid is a weak organic acid such as citric acid, lactic acid, malic acid, ascorbic acid, tartaric acid, acetic acid or succinic acid, or an inorganic acid such as hydrochloric acid, phosphoric acid or sulphuric acid.
  • the acid is a food grade organic acid such as citric acid, malic acid, ascorbic acid, lactic acid, succinic acid or tartaric acid. Mixtures of two or more different acids may be used.
  • the carbonate is any suitable carbonate or bicarbonate with any suitable cation. Examples of suitable cations include metal ions such as calcium, potassium and sodium.
  • the carbonate is a food grade material that is insoluble in water.
  • Quiescent freezing is a relatively slow process. It is important that the carbon dioxide generating composition should not be used up too quickly, so that little or no carbon dioxide is generated during the quiescent freezing process. It has been found that a carbon dioxide composition comprising an acid and a carbonate can be prevented from being used up too quickly by providing the carbonate in the form of particles of a carbonate salt with low solubility.
  • particularly preferred carbonates are carbonate salts with solubility constants in water of 10 "8 or less. Mixtures of two or more carbonates may be used. Most preferably the carbonate is calcium carbonate.
  • the type and amount of acid and carbonate are selected such that the overrun generated in the final frozen product is preferably at least 25%, more preferably at least 40%, without using other methods of aeration.
  • the presence of excessive amounts of carbonates can impart an unpleasant taste to the product.
  • the carbonate content is from 0.1 wt% to 5 wt%, more preferably from 0.5 wt% to 2 wt%.
  • the molar ratio of acid to carbonate is selected so as to have sufficient acid to react with the carbonate present in the premix and generate carbon dioxide to provide the desired overrun.
  • the frozen confection is a water ice, a milk ice or a frozen yoghurt.
  • the frozen confection is a water ice.
  • the total solids content is at least 6 wt%, more preferably at least 8, 10, 15 or
  • the total solids content is less than 35 wt%, more preferably less than 25 wt%.
  • the mix contains less than 1% stabiliser, more preferably less than 0.3%, most preferably less than 0.1 %.
  • the mix contains less than 5% fat, more preferably less than 3% fat, most preferably less than 1% fat.
  • the mix contains less than 5% protein, more preferably less than 3% protein, most preferably less than 1 % protein.
  • the mix comprises a foaming agent.
  • foaming agents are milk proteins and egg white.
  • carbon dioxide generation begins before the mix is quiescently frozen. It has been found that the overrun can be increased by causing carbon dioxide generation to occur for some time before quiescent freezing, provided that the carbon dioxide generating composition is not used up during this time.
  • the mix is partially slush frozen before it is quiescently frozen.
  • Partial slush freezing can be achieved with relatively simple and inexpensive equipment, for example a home ice cream maker. Partial slush freezing can take place before or during generation of the carbon dioxide, provided that the carbon dioxide generating composition is not used up before quiescent freezing. Partial slush freezing increases the viscosity of the mix and thereby helps to delay the escape of the carbon dioxide from the partially slush frozen mix. Alternatively the mix is not partially slush frozen.
  • the mix is placed in a mould or package for quiescent freezing.
  • the mix is quiescently frozen by immersion in liquid nitrogen.
  • One type of water ice product consists of a plurality of discrete frozen pieces packaged together, for example in a tub. Such pieces are produced by dripping a mix through small nozzles into a bath of liquid nitrogen (described in WO96/29896).
  • the present invention also provides a frozen confectionery product comprising a plurality of discrete water ice pieces wherein the discrete water ice pieces are aerated. It has been found that by using the method of the present invention, it is possible to aerate discrete water ice pieces produced by dripping a mix containing a carbon dioxide generating composition into liquid nitrogen. Preferably the discrete water ice pieces have an overrun of at least 2%. It has been found that discrete aerated water ice pieces produced according to the present invention have improved storage stability as evidenced by their flowability.
  • the present invention also provides the use of a carbon dioxide generating composition to aerate a quiescently frozen confection wherein the mix does not comprise a gel.
  • a simple water ice mix was prepared with the following formulation:
  • the water was heated to about 70°C.
  • the dry ingredients were then added and the mix was stirred for several minutes as it was further heated to 82°C and pasteurised by holding it at this temperature for at least 30 seconds.
  • the mix was then cooled to 5°C until required. Some of the mix was frozen (without aeration) and the density of the frozen unaerated mix was measured by method 1 described above.
  • Example 1 1 % (w/w) calcium carbonate particles was added to the mix as follows.
  • the calcium carbonate particles were supplied by Provencale s.a. (B.P. 97 F- 83172, Brignoles Cedex, France) with code name Mikhail SPL, and had a mean size of 20 ⁇ m.
  • the calcium carbonate was weighed out into a beaker and approximately 100ml of water was added and stirred to make a slurry. The slurry was then stirred into the rest of the mix. The acidic mix reacted with the calcium carbonate, and within a few minutes bubbles of carbon dioxide were apparent.
  • the mix was poured into moulds, which were placed in a blast freezer at -32°C. After the mix had frozen the samples were held at -25°C overnight.
  • Example 2 A second mix was prepared with the following formulation.
  • Hyfoama DS is a hydrolysed enzymatically solubilised milk protein (casein) available from Quest, Bromborough, UK. The small amounts of locust bean gum and Hyfoama DS were added so that the formulation was representative of a commercial water ice formulation. The mix was divided into four parts, each of approximately 5 litres.
  • Example 2 1 % (w/w) calcium carbonate particles was added to the first part (Example 2) as described in Example 1.
  • the acidic mix reacted with the calcium carbonate, and within a few minutes bubbles of carbon dioxide were apparent.
  • the mix was poured into moulds, which were placed in a freezer until the mix was frozen. Two different freezers were used, one at -25°C and a blast freezer at -32°C. Comparative examples A and B were produced by adding gelling stabilisers to the mix. 1 % (w/w) gelatin was added to the second part (Comparative Example A). 1% (w/w) of a 50/50 mix of xanthan and locust bean gum was added to the third part (Comparative Example B).
  • Example 2 shows that the samples according to the invention (Example 2) had overruns of at least 26%, i.e. aerated water ices were produced. Comparative examples A and B also had significant overruns. However, these samples had an unpleasant chewy, gummy texture. Comparative example C without the carbon dioxide generating composition had only a very low overrun.
  • the two different freezing regimes used for Example 2 produce different rates of ice formation. The faster freezing regime (the blast freezer) allows less time for the generation of carbon dioxide as the ice is formed, and so produces products with lower overrun.
  • Example 3 In another embodiment of the invention, the mix was partially slush frozen before carbon dioxide generation was caused to occur. A mix was prepared as described in Example 2.
  • Frozen products according to the invention were prepared by partially slush freezing the mix in a scraped surface heat exchanger. Although the mix was not subjected to deliberate aeration, a low level of aeration (less than 10% overrun) occurs as the mix is pumped through the scraped surface heat exchanger. The partially frozen mix was then drawn at about -3.5°C. 1 % w/w calcium carbonate particles with mean size 20 ⁇ m were added into the partially frozen mix as follows. The calcium carbonate was weighed out into a beaker and approximately 100ml of water was added with stirring to make a slurry. The slurry was then stirred into the rest of the mix.
  • the acidic mix reacted with the calcium carbonate, and within 10 minutes there was a noticeable increase in volume due to the generation of the carbon dioxide.
  • the partially frozen mix was divided into four parts which were left to stand in a room at 2°C for 20, 30, 40 and 60 minutes to allow carbon dioxide generation to proceed.
  • the partially frozen mix was then poured into moulds which had been pre-cooled to -25°C (in order to prevent the melting of the ice).
  • the filled moulds were finally placed in a freezer at -25°C. Aerated products were produced.
  • the overruns of the products were measured using method 1 described above and are shown in Table 2. Higher overruns were produced when carbon dioxide generation was allowed to proceed for a period of time before the mix was completely frozen.
  • Example 4 Frozen products according to the invention were also prepared by an alternative process.
  • a mix was made as described in Example 2.
  • 1% w/w calcium carbonate particles with mean size 20//m were added into the mix at 5°C as follows.
  • the calcium carbonate was weighed out into a beaker and approximately 100ml of water was added with stirring to make a slurry.
  • the slurry was then stirred into the rest of the mix.
  • the acidic mix reacted with the calcium carbonate.
  • the mix was divided into three parts which were left to stand at room temperature for 1 , 12 and 50 minutes to allow carbon dioxide generation to occur.
  • the mix was then partially slush frozen in a scraped surface heat exchanger and drawn at about -3.5 ° C.
  • the partially frozen mix was then immediately poured into pre-cooled moulds and placed in a blast freezer at -32°C for three hours, and finally transferred to a freezer at -25°C.
  • Aerated products were produced.
  • the overruns of the products were measured using method 1 described above and are shown in Table 3. Higher overruns were produced when carbon dioxide generation was allowed to proceed for a period of time before the mix was partially slush frozen.
  • Example 5 Frozen products according to the invention were prepared as in Example 3, but using different amounts (0.5, 1, 2, 4% w/w) of calcium carbonate particles. The partially frozen mix was poured into moulds after waiting for 20 minutes, and placed in a freezer at -25°C overnight. The overruns were measured using method 1 described above and are shown in Table 4.
  • Example 6 A mix was prepared using the following formulation (i.e. without any acid):
  • citric acid was added to the first part, so that it had a concentration of 4% w/w; calcium carbonate was added to the second (to a concentration of 2% w/w), and citric acid (to a concentration of 2% w/w) was added to the third.
  • Th e first and second mixes were loaded at 5°C into two separate chambers which each fed into a third chamber.
  • the third chamber was situated above a bath of liquid nitrogen, into which mix could be dropped via a dripping nozzle of 1mm internal diameter.
  • the flow out of each chamber was controlled by taps. The taps on the first two chambers were opened so that the mixes flowed out of them in to the third chamber at the same rate.
  • the third chamber contained a 50:50 mixture of the two mixes, with overall calcium carbonate and citric acid concentrations of 1% and 2% respectively.
  • the tap on the third chamber was initially closed. The acid reacted with the calcium carbonate, and within a few minutes bubbles of carbon dioxide were apparent. After waiting for 10 minutes to allow a head to build up, the tap on the third chamber was opened so that drops of mix fell from the nozzle into liquid nitrogen where they were rapidly frozen into aproximately spherical pieces with diameters of about 3mm.
  • the rate of flow out of the third chamber was arranged to match the rate of flow into it so that a constant head was maintained. Shortly before the mixes in the first two tanks ran out, the pieces of frozen water ice were collected from the liquid nitrogen bath, placed into pots, held overnight at - 10°C and then stored at -25°C (Example 6).
  • the third mix was loaded at 5°C into a chamber of 5 litres capacity which fed directly into a dripping nozzle of 1 mm internal diameter situated above a bath of liquid nitrogen. Drops of mix fell from the nozzle into liquid nitrogen where they were rapidly frozen into approximately spherical pieces with diameters of about 3mm. These were collected from the liquid nitrogen bath, placed into pots, held overnight at -10°C and then stored at -25°C. Since the mix did not contain calcium carbonate, no carbon dioxide was generated (Comparative Example D).
  • Comparative example D had an overrun of 0%; in this case, unlike the scraped surface heat exchanger, no unintentional aeration occurs during the process. Even though their overrun was relatively low, the discrete frozen pieces of Example 6 were noticeably softer than those of Comparative Example D when eaten. After 30 days storage at -25°C, the discrete frozen pieces of Example 6 scored 2 on the free flow test described above, whereas those of Comparative example D had a score of 3 and were noticeably less free- flowing and more sintered. Thus it is apparent that the discrete frozen pieces produced according to the invention have improved storage stability, as evidenced by better flowability after storage at -25°C than the corresponding product which lacks the carbon dioxide generating composition.
